For a personal Azure subscription where Microsoft Authenticator is not providing a usable code and no alternate sign-in option appears, the issue is typically with the MFA configuration on the account rather than the app itself.
From a similar resolved case, the effective remediation was to reset the MFA registration for the affected account from Microsoft Entra ID using another administrator account:
- Sign in to the Microsoft Entra admin center with an account that has Global Administrator rights in the tenant where the personal account is used.
- Go to Identity > Users > All users.
- Select the affected user (the personal Azure account that cannot sign in).
- Open Authentication methods for that user.
- Select Require re-register MFA.
- Have the affected user sign in again; they will be prompted to set up MFA (e.g., Microsoft Authenticator) from scratch and can then register a working method.
In the referenced case, a new Global Administrator account was created specifically to perform these steps, and then the stuck MFA profile for the personal account (added as a guest in the tenant) was reset.
If there is no other Global Administrator available in the tenant, a new admin account must be created or Microsoft support engaged (for example, via the Data Protection team as in similar Q&A cases) so that someone with sufficient rights can perform the MFA reset.
